KM23V4100D(G)  
CMOS MASK ROM  
4M-Bit (512Kx8 /256Kx16) CMOS MASK ROM  
GENERAL DESCRIPTION  
FEATURES  
· Switchable orginization  
524,288 x 8(byte mode)  
262,144 x 16(word mode)  
· Fast access time  
3.3V Operation : 100ns(Max.)  
3.0V Operation : 120ns(Max.)  
· Supply voltage : single +3.0V/ single +3.3V  
· Current consumption  
The KM23V4100D(G) is a fully static mask programmable ROM  
fabricated using silicon gate CMOS process technology, and is  
organized either as 524,288 x 8bit(byte mode) or as 262,144 x  
16bit(word mode) depending on BHE voltage level.(See mode  
selection table)  
This device operates with 3.0V or 3.3V power supply, and all  
inputs and outputs are TTL compatible.  
Because of its asynchronous operation, it requires no external  
clock assuring extremely easy operation.  
Operating : 25mA(Max.)  
Standby : 30mA(Max.)  
It is suitable for use in program memory of microprocessor, and  
data memory, character generator.  
· Fully static operation  
· All inputs and outputs TTL compatible  
· Three state outputs  
· Package  
-. KM23V4100D : 40-DIP-600  
-. KM23V4100DG : 40-SOP-525  
The KM23V4100D is packaged in
